Electroporation efficiency in E. coli

Greetings.
We recently bought an electroporator and have been doing some experiments
to optimize it for our standard E. coli host strains. At present we are
getting about 2 x 10^7 per microgram for HB101 and 10 times that with
MC1061. These numbers apply to two different vectors - a 6.1 kB Dictyostelium
shuttle vector and the Bluescript vector. These frequencies are well short
of the frequencies one is supposed to be able to achieve. My question is -
what are the real frequencies that most people achieve with cells they have
prepared themselves?			Cheers, Paul Fisher.
